Traditional methods for bone pulverization typically generate heat, risking stability of DNA sample. SPEX? has developed cryogenic grinders which introduce liquid nitrogen to cool the sample and aid in the grinding process. In this study, the Freezer Mill 6970 EFM was used with two DNA extraction methods and routine downstream STR analysis procedures. DNA from as little as 0.1 g of bone powder was used to develop full STR profiles after freezer mill pulverization, and the method was reproducible. Further, no contamination was detected upon cleaning/reuse of the sample vials. There were no significant differences in DNA yield, STR alleles detected, or peak heights using the freezer mill as compared to traditional grinding, and successful DNA profiles were achieved from as low as 0.1 g of bone powder with this method. Overall, this work indicates that this cryogenic mill method may be used as a viable alternative to traditional tissue grinders. 相似文献

The empirical evidence on the process-based model of self-regulation shows that procedural justice evaluations and the perceived legitimacy of authorities impact law-abiding behavior. However, few studies analyze this theory from the perspective of adolescent legal socialization. The present study aims to examine the process-based model and other socializing agents such as family, school and peers that may have an effect on it. The sample comprised 2041 youths residing in Spain, aged between 13 and 18 years. The data form part of the Third International Self-Report Delinquency Study (ISRD-3). Multiple linear regression analyses were conducted to predict police legitimacy and juvenile delinquency. The results reveal that police legitimacy perceptions are not only influenced by procedural justice, but also by parental monitoring, school attachment, and delinquent peers. Moreover, perceptions of police legitimacy, parental monitoring, and delinquent peers predict juvenile delinquency. These findings complement and add new explanatory factors to the process-based model. 相似文献

Soil vestiges might provide information about a crime scene. The Rietveld method with X‐ray diffraction data (RM‐XRD) is a nondestructive technique that makes it possible to characterize minerals present in the soils. Soil clays from the metropolitan region of Curitiba (Brazil) were submitted to DCB treatment and analyzed using XRD with CuKα radiation in the step‐scan mode (0.02° 2θ/5 s). The GSAS+EXPGUI software was used for RM refinement. The RM‐XRD results, together with the principal component analysis (PCA) (52.6% total variance), showed the kaolinite predominance in most analyzed samples and the highest quartz contents in “site 1.” Higher anatase, and gibbsite and muscovite contents influenced discrimination, mainly in “site 3” and “site 1,” respectively. These results were enough to discriminate clays of four sites and two horizons using a reduced amount of sample showing that the technique can be applied to the investigation into soil vestiges. 相似文献

This article analyses, defines, and refines the concepts of ownership and personal data to explore their compatibility in the context of EU law. It critically examines the traditional dividing line between personal and non-personal data and argues for a strict conceptual separation of personal data from personal information. The article also considers whether, and to what extent, the concept of ownership can be applied to personal data in the context of the Internet of Things (IoT). This consideration is framed around two main approaches shaping all ownership theories: a bottom-up and top-down approach. Via these dual lenses, the article reviews existing debates relating to four elements supporting introduction of ownership of personal data, namely the elements of control, protection, valuation, and allocation of personal data. It then explores the explanatory advantages and disadvantages of the two approaches in relation to each of these elements as well as to ownership of personal data in IoT at large. Lastly, this article outlines a revised approach to ownership of personal data in IoT that may serve as a blueprint for future work in this area and inform regulatory and policy debates. 相似文献

This article analyzes the developmental impact of two of the earliest investments made by Chinese companies in South America, the Shougang Corporation's mining activities in Peru and Andes Petroleum's oil extraction operations in Ecuador. The article draws attention to the importance of contextualizing and disaggregating instances of Chinese resource‐based investment in order to adequately grasp the complexity of processes that are contingent to particular regimes of natural resource governance, companies' backgrounds, and the strength and nature of local reactions, among other factors. It thereby encourages a critical examination of Chinese investment in South America that explores how the characteristics of that investment are reshaped by the long and contested histories of resource extraction in the region, the promotion of and resistance to particular visions of development, the agency of multiply situated and complex actors, and the wider transnational production networks in which resource extraction processes are embedded. 相似文献

After the period of hyperinflation (1989, 1990) the Argentine economy stabilized and most of public companies were privatized. The return on investments was concentrated on promoting the technological change which adopts two basic forms: systemic modernization and revamping of existing teams. The first variant -ilustrated by the national telephone network- makes obsolete the knowledge accumulated during the period when the company was public. To confront the structural deficiency of knowledge and experience which result, the private operators invest massively in transfering educational technologies and in the development of costly and sofisticated internal systems of training, while they negotiate numerous and various agreements of cooperation with educational system institutions, public as well as private. In the second variant - illustrated by a steel and metallurgic company - the preexisting knowledge continues being necessary even though it may need a vis-a-vis updating facing the new demands which are stated referring to the productivity, quality, effectiveness and productive efficiency in markets which are open to competition. Taking into account the significant achievements which are being obtained by this second alternative of modernization - most of the privatized companies fall into this pattern- the article invites to a reopening of the old debate on technological blending. 相似文献

This article investigates brand architecture by analyzing stakeholder perceptions of brand images when a new joint brand is created for the existing brands of three arts organizations. The theoretical framework is based on previous literature on brand architecture and brand image. The empirical study is based on a quantitative, 418-respondent survey among stakeholders of these three arts organizations. The study makes two major theoretical contributions. First, the results show that the new joint brand can be endorsed by the existing sub-brands, contrary to brand-architecture literature. Second, even in the case of a new brand, stakeholders perceive the functional attributes as important. 相似文献

Abstract Immature moral judgements, cognitive distortions and low empathy could contribute to criminal offending and are often targeted in interventions aimed at reducing risk of recidivism. We compared 58 delinquent 13–18-year-olds, incarcerated in youth homes in Sweden (29 males, 29 females) with 58 (29 males, 29 females) community control adolescents individually matched on age, gender, ethnicity and socio-economic position. Self-report questionnaires examined moral judgement, cognitive distortions, and empathy. Delinquent adolescents exhibited less mature moral judgements and more cognitive distortions than control adolescents. However, no association between delinquency status and self-reported empathy was found. In addition, girls reported more mature moral judgements, less cognitive distortions and more empathy than boys did. Moral judgement and empathy were positively correlated and both measures were negatively correlated with cognitive distortions. Our data support the idea that moral judgement and cognitive distortions are important treatment targets for juvenile delinquents, whereas empathy may be less meaningful to address directly. 相似文献
